Ecological performance optimization of a generalized irreversible thermoacoustic cooler with heat resistance, heat leakage, thermal relaxation and internal dissipation, in which heat transfer between the working fluid and heat reservoirs obeys a complex generalized heat transfer law <inline-formula><inline-graphic xlink:href="ctp038ileq1" xmlns:xlink="http://www.w3.org/1999/xlink"/></inline-formula>, where n is...

To reveal the physical mechanism of the thermoacoustic oscillation is an important task of basic research on thermoacoustics. The startup process of a thermoacoustic oscillation is a parametric excitation process. The so-called “parameter exciting” refers to that the oscillation process is...
